Search for Superheavy Elements in Nature and in Heavy Ion Reactions

摘要: The following experiments were carried out: I) Experiments using heavy ions of the UNILAC / GSI. I.1) “Gas-jet experiments”,: In interactions (Xe+U) and (U+U) exactly ZERO fission fragments high-energy alphas are observed: σ (SHE)≤ 5.10−33 cm2 for 3s 50μm) halos; however, exclusively around big inclusions, suggesting possible non-nuclear origin some giant halos. Alpha- fission-fragment measurements one sample containing halo do reveal any or alpha particle E> 9 MeV7). II.4) High-energy monazite from Madagaskar: Using simple ∈ -counter, see “high-energy” (E 1e5MeV) such samples. When use d E-E counter-telescope, only observe well-known energies <1e5MeV), so far. These continued.
